What Is Convex Finance? How CRV Boosting, cvxCRV and vlCVX Work

The problem Convex solves

Curve pays its liquidity providers in CRV, and a provider's CRV rewards can be boosted up to 2.5 times the base rate if the provider also holds veCRV, which is CRV locked for between one week and four years, per Curve's documentation. Most liquidity providers do not want to lock CRV for years just to raise their yield. Convex holds a large, permanently locked veCRV position and applies its boost to everyone who stakes LP tokens through it.

In exchange, Convex takes a cut of the CRV those deposits earn and pays depositors an additional reward in CVX. The arrangement also concentrates voting power over Curve's reward allocations ("gauge weights") in Convex, which is why CVX holders who vote-lock their tokens are courted by protocols that want Curve rewards directed to their pools. Readers new to liquidity pools can start with OBOL's AMM explainer.

How Curve liquidity providers use Convex

Per the Convex deposit guide:

1. Provide liquidity on Curve and receive the pool's LP token.
2. On convexfinance.com, open the Stake tab and pick the matching pool under "Stake Curve LP Tokens."
3. Approve the LP token once, then deposit and stake.
4. Claim CRV, CVX and any extra incentive tokens as they accrue.
5. Withdraw at any time from the pool's Withdraw tab; there is no lock-up on LP deposits.

Convex charges no deposit or withdrawal fee and takes no cut of extra incentive tokens that a pool pays on top of CRV. Ethereum gas costs for approvals, deposits, claims and withdrawals still apply and can outweigh rewards on small positions. The underlying Curve pool exposure, including impermanent loss and stablecoin de-peg risk, does not change by staking through Convex.

cvxCRV: tokenized CRV with a one-way door

CRV holders can deposit CRV into Convex, which locks it permanently as veCRV and issues cvxCRV one-for-one. Staked cvxCRV earns crvUSD from Curve's admin fees plus a share of Convex's CRV and CVX fees, and stakers can set their reward mix anywhere from all crvUSD to all CRV/CVX, per the cvxCRV documentation.

The conversion is irreversible. Convex offers no route back from cvxCRV to CRV; the only exit is swapping on a liquidity pool, where cvxCRV can trade below the value of one CRV. That discount is the main cost of cvxCRV and the detail new users most often overlook.

CVX and vote-locking

CVX is the protocol's governance and reward token, with a fixed maximum supply of 100 million, per the tokenomics page:

The amount of CVX minted per CRV declines as total CVX supply grows, so new emissions shrink over time.

To vote or receive the CVX share of platform fees, holders lock CVX as vlCVX. A lock lasts 16 weekly epochs, each starting Thursday at 00:00 UTC. Newly locked CVX gains voting weight only from the next full epoch. After the lock ends, tokens sit in the contract until withdrawn or relocked; if they are left idle beyond a four-epoch grace period, anyone can "kick" them out and collect a 0.25%-per-epoch bounty, according to the vote-locking documentation.

Frax and f(x) Protocol

Convex applies the same model to Frax Finance, holding veFXS and issuing cvxFXS, and to f(x) Protocol, issuing cvxFXN for its FXN token. Frax liquidity providers can stake through Convex for boosted FXS rewards. Each integration has its own fee split and its own platform risk.

Fees

Convex earns money by taking a percentage of the governance-token rewards it boosts. Its fee page gives these splits as of October 2026:

Convex quotes current and projected APRs in its interface. These are variable and depend on CRV and CVX prices, pool incentives and gauge votes; they are not interest rates and are not guaranteed.

Who controls Convex

Admin functions sit with a 3-of-5 Gnosis Safe multisig. Its signers, per the multisig page, are C2tP and Winthorpe from Convex, plus representatives of Llama Airforce, Votium and Frax Finance. The multisig can add new pool types, change fee splits within hard-coded limits (the total cannot exceed 20%), vote Convex's veCRV in Curve governance, manage treasury funds and vlCVX reward settings, and pause or shut down deposits. Convex states that the multisig has no direct access to user deposits and that a shutdown leaves users able to withdraw. That is the project's own description; it has not been independently verified for this profile.

Audits and risks

Convex lists audits by MixBytes (core platform, April 2021), PeckShield (Frax staking, wrapper and sidechain contracts, 2022), Nomoi (cvxCRV staking wrapper and sidechain, January 2023) and ChainSecurity (a Silo Finance wrapper, April 2023), per its audits page. The audits cover specific contracts at specific times; they do not certify later code or integrations.

The protocol's own risk page names three categories: smart-contract bugs, a non-zero chance of losing some or all funds, and inherited risks from Curve and Frax. To those, a reader should add:

• cvxCRV discount: the one-way conversion leaves holders exposed to market pricing.
• Lock illiquidity: vlCVX cannot be withdrawn before its 16 epochs end.
• Governance concentration: Convex's large veCRV position means its vote-locked holders, and those who pay them for votes, shape Curve rewards.
• Phishing: fake front ends are common for DeFi protocols; use the official domain below and check approvals. OBOL's DeFi primer covers wallet approvals in general.
